Application filed June 30, 192D. Serial No. 393,010.

T0 all 'io/tom t may concerti Be it known that l, Yfiiaiunnn lViLLiAiis,.

a citizen of the United States0 and resident of Sanl Jose, in the county of Santa Clarav and State of California, have invented certain new and useful Improvements in Amusement Devices, of which the following is a specification.

My' invention relates to an amusement devvice .involving a combination of revolving the casemaybe; in which the same 'member is caused to revolve with an undulating move-L ment'by the operator thereofgin which resilient means are utilized for normally holdingthe revoluble member in a horizontal position; in which a novel forni of bearing' is provided whereby the desiredfreedoin of action is secured and theeffective life ofy thefdevice prolonged. Finally it is the objectfof my invention to provide a device of the character vrindicated that will be simple in fform', economical yto manufacture, durable, and highly etlicient in its practical application. i

In the drawingz- I Figure'l is a plan view of one embodiment ofv my invention, part being'broken away.'l

Figure 2 is a section on line 2-2 of Figure 1`.

Figure 3 is aside elevation of another embodiment of my invention.

Figure 4 isa side elevation of still another embodiment of my invention. y

Referringmore particularly` to the drawing, 1 indicates a base member upon which is bolted abearing member 2 having an invertedtruncated cone shaped socket formed in the' upper surface thereof as shown at 3 and havinga vertically' and concentrically positioned'post 4 cast' integrally therewith asfshown, and 'having annular-grooves 5 A'foiii'iied' thereinl to receive ball bearings 6 as shown.

At 7 is shown an inverted truncated cone shaped member mountedto revolve on post 4 and positioned within and space-d a distance from socket 3 and supported on balls 6. Member 7 carries a ange 8 extending a distance beyond the outer and upper edge' y of bearing member 2 and spaced a distance above the same. Member 7 also has an upper portion 9 rising a distance above liange 8 as at 10 and provided with a conveXly rounded surface 11 concentrically arranged with.` respect to post 4.

At 12 l show a circular platform having a substantially larger diameter than flange 8 and preferably built up of boards 13 secured together by cleats 14 and having a re-Ay inforcing and bearing plate 15 arranged concentrically thereto on its under surface. llatform 12 and plate 15 are provided ,with an orifice 16 at the center thereof ofsome what larger diameter than post n 4 over which these members are placed so as to rest on the rounded surface 11 of member 9.

A collar 1'? is secured to post 4 a distance above platform 12 to prevent the wilful removal of saidplatform from said post.

At 18w-1S-18-18 are shown bolts secured at their upper endsto platform .12"

andv plate 15 by nuts l9`and extending downwardly through vorifices 20in iian'geV andA terminating 'a distance below said flange and fitted with washers v21.

inserted between washer 21 and a second washer 23 engaging the under side of flange 8. ln the embodiment shown in' Figures 1 and 2 the upper` end of post 4 is fitted with a cap member 24 threaded at 2.5 to en` gage kthe threaded ends of laterally projecting 'pipe members 26,'the latter being four ln this-einlarge tov permit'the free tilting of said platform without theedge of said orifice enf gaging said post. .Also since bolts 18s-184- Each bolt 18*k lis ttedwith fa spring 22, the same being at 28, the orifice 16 must be'made sufliciently ioo and tilt therewith the orifices 20 throughwhich they pass must also be made "sufficiently large to permit the free tilting of ing force to cleats 27 with their feet. Since tlierodsor arms 26 are stationary the platforml2 is caused to revolve after the inanner of aitreadmill. r.The platform may also be propelled by the children sitting on the edge thereof Land applying their feet to the ground. t is clear of course that when Aplatform l2 revolvesv the several members 15-9-19-8 and 7 revolve with it,V about stationary post i and on bearings 6. Since nol grooves are formed for balls 6 in cone shaped member 7 any wear incident to continued use ofthe devi-ce is automatically compensated for by the settling of member 7 further into socket 3. The rotating `movement of platform l2 is imparted to member 't' through the rmedium of bolts 18 and frictional contact with the upper part of surface ll. i

lf a weight is applied to any portion of .platform l2 suficient to over balance the same, .as for instance the weight of a child at 29,*then ythe bolt orbolts 18 on that side take a tilted position as shown in dotted vlines'at 30, and bolts 18 on the opposite .side to the `said weight take a position as "indicated at 31,k placing their springs 22 under compression.

The result of this construction is that the platform l2 will revolve `freely at all times and by proper manipulation as in play the saine may be lcaused to assume aninfinite variety of angular positions, but will always automatically assume ay substantially horizontal position when at rest.

In Figure 3 I show an embodiment of my invention in which post 4; is omitted. In this embodiment the bearing member is supported a distance from the ground by legs 32 and a cap member 33 is held in position on.

`surface ll of member 9 by. bolts 18, the cap member 33 having a number of radially arranged bars 34C iixedly secured thereto. In this case the cap member 33 and bars 34 operate on surface 11v and with rotating memyber v7 9 in exactly the same manner as platform 12 described in connection with F igures 1-2. f

The loperation of the structure shownin. Figure i is identical with that describedv in ,p connection with Figure 3 except that each bar 34: carries a swing 35 provided with a bumper 36, the swings being pivotally con-V nected to said bars `at 37.v i y It is understoodof course that changes in C form, construction and arrangement of vthe ments rigidly secured toone of said members and passing through the other member, Y

and a resilient connection between each of said elements vand said last mentioned member.
